Thanks for all the info. yea you got my head spinning a bit. lol. I am getting 25 mpg with 235 tires with MAF unplugged which is about what its always got. i want to fix this problem cause i just don't like things that don't work right. The vacuum and or leaf blower is a great idea. i will have to try that or what do you think about putting a calibrator on the input wire(MAF) going back to the ECU. With the MAF unplugged i can simulate a MAF. i use one of these to test electrical equipment. i can source a 0-5vdc signal back to the ECU and that would tell if my MAF is no good or something else. When i checked the MAF, i was getting 1.4v with key on and 2.0v at idle. i could get the signal to go up to about 2.5-2.8 when i gave it gas but that was about it before it would die. i am going to have to get a fuel pressure gauge at harbor freight as i am having trouble getting my hands on one.
